COMBUSTION DEVICE.

To all whom-it may concern:

Be it known that I, W'ILLiAM S. BARNETT, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented a new and useful Combustion Device, of which the following is a specification.

The structure forming the subject matter of this application is a combustion device of that type shown in my prior Patent No. 1,1,52,691, issued on the 7th day of September, 1915.

The structure forming the subject mat ter of this application is adapted to be employed for converting oil into gas, the gas subsequently being burned.

The advantages of the present structure, so far as its general shape is concerned, have been dealt with in my prior patent, and need not be repeated in this specification. It may be stated, however, that, owing to the particular shape of the structure, it has become necessary to reduce the number of joints, to prevent leakage and to render the device more efficient. The structure is of peculiar outline and it has been found, after extended experiment, that, owing to the general outline of the device, integral connections must be used to obtain the best results and to avoid leakage, in parts where tion.

In the accompanying drawings :Figure 1 shows the invention in top plan, parts being broken away; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a section on the line 3-8 of Fig. 1.

In the accompanying drawings, the numeral 1 indicates a fuel supply pipe carrying casings 2 provided with valves 3. The casings 2 are connected by means of nipples 4:, with generator casings 5, the casings 5 preferably being united integrally as, shown Specification of Letters Patent.

Serial No. 90,715.

at 6. It has been found, in practice, that leakage is likely to occur at the rear ends of the generator casings 5, and at this point, one of the present improvements characteristic of the invention is inserted.

The generator casings 5 at their rear ends 7 are provided with integrally formed depending extensions 11, thus doing away with elbows at this point. The lower ends of the depending extensions 11 are received in elbows 15. Cooperating with the elbows 15 are pipes 17 located below the casings 5 and extended in opposite directions, away from the generator casings. The pipes 17 are connected integrally with pipes 2a which lie below the generator casings 5 and extend parallel thereto. A leakage is likely to occur at the points where the pipes 17 and 24: are jolned, and in this connection it will be seen that the pipes 17 and 24 are integrally connected, as shown in Fig. 1. Intermediate their ends, the pipes 24: are supplied with burner tubes 30 carrying caps 31 having burner orifices 32.

Another point of weakness in the structure hereinbefore patented, arose out of the fact that a leakage was likely to occur where the pipes 30 and 24 are joined. In this form of the invention, the parts 30 and 24: are integrally connected, as will be obvious from Fig. 3. The outer ends of the pipes 24 are made solid, as shown in Fig. 3, and with these solid ends are integrally connected, sockets 25. Owing to the constructlon above outlined, the possibility of leakage is reduced to a minimum.

The lower ends of the angle brackets 26 are inserted removably into the sockets 25, without threading, the construction being such that the angle brackets may be inserted into the sockets and be removed readily therefrom. The angle brackets 26 carry defiectors 27 located above the orifices 32 in the caps 31. By rotating the stems of the angle brackets 26 in the sockets 25, the deflectors 27 may be positioned properly with respect to the orifices 32. The tubes 30 are surrounded by hoods 50, supported on the pipe 24 and notched as shown at 51, to receive the said pipes.

Packings 10 may be placed in the genera- I fact that the ends 11 are integral with the formed upright socket, said other pipe being generators 5, and in the fact that the parts 17, 24, 30, and 25 are formed in one piece.

The foregoing improvements have been found, in practice, to enhance the utility of a device of the type herein disclosed.

Having thus described the invention, what is claimed is In a device of the class described, a generator provided at one end with an inte grally formed depending extenslon; an elbow .wherewith the extension coacts; a

f larly disposed pipes integrally connected at their point of juncture, one end of one pipe coacting withthe elbow, the other pipe being terminally provided, with an integrally Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patent Washington, D. G.

provided intermediate its ends with an integrally formed upstanding burner tube and lying below the generator and in approximate parallelism thereto; and an angle bracket, the lower end of which fits smoothly and for rotation in the socket the other end of the angle bracket being provided with a deflector located above the burner tube.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses, one-piece structure comprising two angu- WVILLIAM S. BARNETT,
